Tailored Services – R&D Projects Solar Activity ASSA : Automatic Solar Synoptic Analyzer solar cycle prediction Solar Wind WSA-Enlil + Cone (Dr. Dusan Odstrcil & SWPC) IPS Solar Wind Reconstruction (Dr. Bernard Jackson & STELab. of Nagoya Univ.) Satellite GEO environment monitor LEO satellite drag prediction Aviation radiation dose prediction Power Grid local GIC map Navigation local TEC map local GPS ionospheric error map Communications local ionospheric model (IRI-2012 + VOACAP + local data) real-time usable HF frequency

Tailored Services – for satellites GEOs Environment Monitor (Dev: 2012) Tsyganenko 2004 & Shue 1998 model Latest ACE SW and Kyoto Dst index Supports KSAT 5 & 6, COMS, MBSat, Intelsat 8, GOES, SDO LEOs Satellite Drag Prediction (Dev: 2013) Thermospheric mass density distribution Global map, Time series, & Vertical profile

Tailored Services – for aviations Polar route SWx monitor (Dec 2013~) live flight position tracking for each flight number (for Korean Air & Asiana Air) provide HF attenuation (D-RAP+PCA) & radiation dose rate (CARI-6) ARMAS-Lite Project (2014~) Automated Radiation Measurements for Aviation Safety fly with airplanes of NOAA & NCAR comparison with NAIRAS model

Tailored Services – for HF communications Ionosphere & HF Model (Dev: 2013~2014) IRI-2012 (empirical) + VOACAP (propagation) + Ionosonde data assimilation real-time usable HF frequency for airlines, ships, military, etc Data assimilation coverage is expended to East Asia in 2014 Way Pt.#2 Way Pt.#1 Way Pt.#3 Way Pt #1 Way Pt #2 Way Pt #3 Tx Rx Way Pt #1 Way Pt #2 Way Pt #3 Seoul Radio Station Lat.

National Preparations Space Weather Response Guideline (2012) describes possible damages from space weather suggests example actions to prevent/minimize damages 5 areas : satellite, airline, navigation, power grid, communications National Plan for Space Weather (2012) vision : “Safe Korea without Space Weather Disaster” 5-year plan (2013-2017) - provides accurate forecasts & real-time alarms - develops advanced models - expands observation networks - space weather awareness-raising

National Preparations Space Weather Disaster Management Manual (Feb. 2013) space weather was included in the national risk profile the government’s official manual was approved - describes the roles & responsibilities of related ministries and agencies - removing confusion & increasing efficiency among different organizations President National Emergency Management Committee (Prime Minister) Ministry of Science, ICT and Future Planning Korean Space Weather Center Other Ministries
